Experimental combo targets Tough-to-Treat colorectal cancer
NCT ID NCT06654037
First seen Jun 25, 2026 · Last updated Jul 31, 2026 · Updated 3 times
Summary
This early-phase trial is testing whether combining two drugs—abemaciclib and 5-fluorouracil—is safe and tolerable for people with advanced colorectal cancer that has spread and stopped responding to standard treatments. About 39 participants will receive the combination to find the best dose and watch for side effects. The goal is to see if this approach can control the disease when other options have failed.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- abemaciclib and 5-fluorouracil
- What this could lead to
- If this combination proves safe and effective, it could offer a new treatment option for patients with advanced colorectal cancer that has stopped responding to standard therapies.
- What could go wrong
- This is a very early (Phase 1) trial with only 39 participants, so the main goal is safety and dosing, not proof of benefit. The cancer is aggressive and heavily pre-treated, so even if safe, the combination may not shrink tumors or extend survival.
